What should you know about wet dandruff treatment?

Dandruff flakes may cling together when mixed with scalp oil, sweat, styling products, or moisture. Seborrheic dermatitis can add redness, itch, and greasy scale around the scalp, hairline, eyebrows, ears, or beard area. Thick adherent scale, marked inflammation, broken hairs, sores, or patches beyond the usual dandruff areas may need assessment for another scalp condition.

The goal is to loosen and control scale while calming irritation. Scraping at the scalp can cause small injuries and make inflammation worse, so the appearance alone should not determine which product you use.

Wash the scalp regularly with a gentle routine and rinse styling products thoroughly. A pharmacist or clinician can recommend a medicated shampoo or topical antifungal treatment when appropriate, including how long the product should stay on the scalp and how often to use it. Apply products to the scalp rather than only the hair, avoid vigorous scratching, and stop a product that causes burning or a new rash. Keep combs and towels clean while symptoms are active.

Arrange a dermatology review for scalp pain, pus, bleeding, marked redness, hair loss, broken hairs, thick plaques, or a rash spreading to the face or body. Seek prompt advice if symptoms began after a new product and include swelling or blistering. Review treatment when flaking and itch continue despite careful use of an appropriate shampoo or return frequently.

Is this dandruff or seborrheic dermatitis? Which shampoo or antifungal suits my scalp? How long should I try it? What signs would suggest infection or another condition?
